Compile the code below, and with the command 'man <program>', you
can view man pages with your web browser, 'less' or 'notepad'. (depending
on how you set the MANHANDLER environment variable) Read the header
below for more info, or hack into the code yourself.

/*
** Title: man.c
**
** Author: Joseph Banta, Perceptics Corp., Knoxville, TN, June 1998
** joe_banta AT perceptics DOT com
**
** Usage: man [-m|--manonly|-i|--infoonly] <names...>
**
** Prerequisites:
** cygwinb19.dll
** bash, tkinfo, wish, sed
** groff (if you want to view man pages via less or notepad;
** otherwise, set the environment variable MANHANDLER
** to the complete path of your web browser
** [i.e., 'c:\Progra~1\MSIE\iexplore.exe'])
**
** Purpose:
** This is a 'man' emulator written for win32, cygnus style.
** It was originally based on 'man2html' by dj AT delorie DOT com,
** but its functionality is extended a bit. What it does is
** search through the directories in the environment variables
** INFOPATH and MANPATH for info and man pages, respectively,
** and if an info page is found, 'tkinfo' is called, otherwise
** the application named in the environment variable MANHANDLER
** (by default, 'less') is called to view the man page. If the
** MANHANDLER application contains the string 'iexplore' or
** 'netscape', then this program converts the man page to html
** format for the browser. If the MANHANDLER application name
** contains the string 'more' or 'less', the man page is piped
** through groff to be viewed appropriately. Otherwise (i.e.,
** if MANHANDLER is defined as 'notepad'), the page is piped
** through groff into plain text format.

" the application named in the environment variable MANHANDLER\n",

" MANHANDLER application contains the string 'iexplore' or\n",
" 'netscape', then this program converts the man page to html\n",
" format for the browser. If the MANHANDLER application name\n",
" contains the string 'more' or 'less', the man page is piped\n",
" through groff to be viewed appropriately. Otherwise (i.e.,\n",
